IMPROVEMENT IN HARVESTER-RAKES.

Specification forming part of Letters Patent No. 147,840, dated February24, 187i; application filed september 6, 1873.

To all whom it may concern Be it known that we, WM. M. and G; H. HOWE,of Lansing, in the county of Mower and State of Minnesota, have inventeda new and useful Improvement in Baking Attachment to Harvesters, ofwhich the following is a specification:

The improvement in the raking apparatus consists of teeth arranged toproject from the rake-head vup through slot-s in the apron, and to swingdown horizontally at the beginning of the backward movement to passunder the grain accumulated on the platform during the forward movement,and then swing up and be locked automatically at the beginning of theforward motion, so as to carry the grain forw ward.

Figure lis a plan view. Fig. 2 is a vertical section. Fig. 3 isalongitudiual sectional elevation; and Fig 4, a longitudinal verticalsection of rake and part of platform.

Similar letters of reference indicate corresponding parts.

A represents a metal plate with the ends B bent up at right angles toit, and fitted, as shown in Fig. 3, to the way C, under the platform, toslide forward and backward, while being securely confined in said way.Above this plate, but below the way O, is the rakehead, consisting of ashaft, D, with the raketeeth E attached to it. Said shaft extends acrossthe plate in the transverse direction of the platform F, and is itted inbearings on the plate, so as to revolve to turn the teeth up into theworking position, and down again. G is a short arm rigidly attached tothe shaft D, and jointed at its free end to a link, H, which is jointedto a sliding bar, I, a little longer than plate A, and supported in theends B, of said plate having mortises through which it passes, so as toproject at each end beyond said plate, as shown in Fig. 4. This barstrikes against the ends J of the raceway before the plate A and therake-stop, to shift the teeth down and up, as represented in Fig. 3,which is the position when the rake is carrying the grain forward to theright. The bar, being arrested at the right-hand end of the race, willswing link H back, which will pull arm G up, and throw the teeth downbackward to the position for going back under the grain. Just beforestopping in the backward movement the bar I, being arrested as before bythat end of the race, will throw the link H forward, the arm G downward,and the fingers upward into the position represented in Fig. 3, ready torake the grain forward again. It will bc seen that the link H stands atright angles to the bar I, so that the teeth are locked against beingforced down by the resistance upon them, as the force, no matter howgreat it is, is delivered by link H, upon bar I, exactly at right anglesto the direction in which it moves, so that it cannot be shifted by saidforce.

To operate the rake, it is connected by link K with the lever L, whichis pivoted at M, and connected near said pivot by rod N, with the arm O,of a rock-shaft, I), which has an arm, Q, extending down through a bar,R, pivoted to the frame at one end, and at the other end, S, fitted intothe groove T of the cam U on the axle of the traction-wheel V. Thesecontrivances cause the rake to move forward once at each revolution ofthe traction-wheel, and gather up the grain into a gavel, and deliver itto the binding-rope and the compressing-arm.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- '1. The combination of the shiftingbarl, linkH, and arm G, with the tiltingrake D E, and the reciprocating carrier A,substantially as specified.

2. The vibrating bar It, arm Q, rock-shaft I), crank-arm O, link N, armL, and link K, combined with the rake-carrier A, and the cam T,substai'ltially as specified.
